A belt separator, sometimes known as a belt grader, can sort round material from non-round material, and rough surfaces from smooth surfaces.
Product is fed from a hopper on to a vibration feeder tray. The product then falls on to a tipped, moving, flat belt. Round/smooth products runs off the side of the belt into containers while the non-round debris stay on the belt and fall off the end.
For example, the belt grader can separate round, vegetable seeds from weed seeds, and rounded ceramic beads from broken or chipped beads.
